WILLIAM ALEXANDER FRASER, OF GEORGETOWN, ONTARIO, CANADA.

FLUSI-IING-TANK.

Specification of Letters Patent.

Patented Dec. 17, 1912.

Application filed November 8, 1911. Serial No. 659,153.

To all whom it may concern:

Be it known that I, WILLIAM ALEXANDER FRASER, of the town of Georgetown, in the county of Halton, in the Province of On tario, Canada, have invented certain new and useful Improvements in Flushing Tanks, of which the following is the specification.

My invention relates to improvements in flushing tanks, and the object of the invention is to devise a flushing tank and water controlling mechanism therefor, which will entirely dispense with the intake valve commonly known as the ball float valve.

A further object is to make the tank compact in form and size, and independent of variation in pressure.

A still further object is to provide a sanitary antiseptic device, which will insure the reflush water in the bowl being antiseptic.

My invention consists of a tank having a main water supply pipe, a main flush pipe to thebowl, a cylindrical float provided with a suitable valve designed to rest upon a seat at the top of the flush pipe, a controlling lever, and a controlling disk designed to coact with the valve, an air outlet at the top of the tank provided with a cylindrical valve and extending at the bottom into a flow pipe, a valve communicating with the interior of the tank and to the air valve designed to control the water passing to the bowl to reflush it, a casing located interme diate of the length of the air pipe and containing a suitable antiseptic substance designed to disinfect and render odorless the reflush water as it passes to the bowl, the parts being otherwise constructed and arranged as hereinafter more particularly explained.

Figure l, is a vertical section through my flushing tank. Fig. 2, is a similar view showing a slight modification. Fig. 3, is a perspective detail partially in section showing the main float valve. Fig. 4, is a perspective view mostly in sect-ion showing the air pipe valve. Fig. 5, is a detail showing the valve for controlling the re-fiush water. Fig. 6, is a perspective detail of the valve support shown in Fig. 5. Fig. 7, is an enlarged view showing the antiseptic casing on the air pipe.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the tank, which is closed both at the bottom and top being provided with a threaded orifice A at the top and a plain orifice A at the bottom.

B is the float cage, which has side guidebars B and a top B C is the top portion of the main flushing pipe, which is provided with a flange C whereby it is secured to the bottom of the tank, a spider C with a central orifice C and a seat (1* at the top provided with an annular shoulder C against which the bottom edge of the cage abuts.

Dv is the float, which is preferably cylindrical in form and has a cone-frustum shaped bottom D to which is secured the disk valve E preferably made of rubber and having an annular space E to make it more flexible and press more tightly on the seat C The disk valve E is secured in place by a rod F having a flat head F, such rod extending upwardly through the cylindrical float D- and being held at the top by a nut and washer. The flush pipe C is provided with a lateral off-set portion C in which is fulcrumed the arm G on the pin G, the outer end of which has connected to it the operating lever arm G The inner end of the arm G has a slot-ted connection to a rod H, which extends through the hole C in the spider C and has secured to the upper end a spider H.

I is the main water supply pipe. This pipe I, I provide with a globe valve I having an indicating pointer I whereby the globe valve may be turned any desired distance to indicating points 1 so as to make the orifice through the valve larger or smaller according to the quickness with which it is designed to fill the tank. This valve is provided, where my flushing tank is arranged in connection with a reservoir especially used in railway coaches.

The threaded orifice A at the top of the tank A carries a valve casing J having a bottom spider J and a top elbow like orifice J J is a cylindrical float normally sup ported on the spider J and provided at the topwit-h a ring J 4 attached to or forming part of a spider-like support J which may form part of the cylindrical casing J On the top of the ring J is arranged a valve J 6 preferably of rubber.

The casing J is provided at the top with a nipple J and to this is connected a pipe K, which extends either inside or outside of the tank A. I have shown it on the inside. At the bottom of the pipe K outside the tank I provide a supplemental separable casing L, which is threaded at the top on to the pipe K and is provided with a flange L by which the upper portion is I the casing L the washers may be-placed in position.

K is an elbow-like extension of the pipe K located inside of the tank A and provlded I with a recessed enlargement K N is a valve having a spiderlikebottom N and a ring-top N surmounted by a disk valve N and held-on the top of a spiderK at the bottom of the enlargement K In Fig. 2, I also show the style of valve used in connection with the main float,

which I use where the tank is under pressure, such as from a city main. In this formI make the disk valve D with a central orifice D the float D carrying the central rod F which extends through the float to a disk F having a central opening F Upon the depression of the lever G and consequently the raising of the rod II the float is first raised without raising the disk valve and the water under pressure passes through the orifice D 'and orifice F*. This serves to relieve the pressure on the disk valve D so that when the disk F reaches it the valve being relieved of pressure may be readily removed from its seat and allow of the water to pass underneath the same.

- involved in my invention I shall briefly describe its'operation and utility.

Referring to Fig. 1, the water passes through the pipe I into the tank and rises in the tank. The displaced air in the meantime passes outwardly around the valve J 3 and through the pipe K and down into the Copies of this patent may be obtained for flushing pipe C. This passing of the air has risen sufiiciently high in the tank to raise the valve J and close the orifice by means of the valve J During this period the pressure of the water in the tank is not at first sufficient to close the valve N so that the water coming into the tank will partially pass through the elbow K and will trickle down through the pipe K into the flush pipe C permeating on its way the antiseptic disks M and carrying with it a certain amount. of disinfecting fluid, which passes into the bowl in the closet, and, therefore, will keep it sanitary. WVhen the water has reached a sufiicient height the pressure on the valve N will cause it to close and stop any more reflush water passing. It will, of course, be understood that the orifice in the elbow K is comparatively much smaller than the orifice in the pipe I from which the pipe is fed.

It will be seen from this description that by the means, which I employ for operating my float and valve, that it is not necessary to have any packedjoints, or separate opening to the tank, which minimizes the liability of leakage. It will also be seen from this description that I am enabled to fill the tank very quickly, and without any air pressureon the water as it passes to the tank as the air is drawn off as the water rises.

Another advantage in my invention is that the operatmg lever is always restored to normal by the fall of the valve on to its seat.

What I claim .as my invention is:

1. The combination with the tank and flushing pipe, of an air pipe, extending within the tank from the top of the tank down to the flushing pipe, and a valve for closing 1 the air pipe at the top of the tank upon the i rising of the water in the tank, an elbow on the air pipe located intermediate of its orifice, an enlargement formed on saidellbow, a valve located within said enlargement and beneath said orifice, a second enlargement formed on the lower end of said air pipe adapted to receive antiseptic material.

Having now described the principal parts 5 2. The combination with the tank and T flushing pipe and inlet pipe, of an air pipe extending from the tank to the flushing pipe, of a conduit leading to the air pipe and provided with a suitable valve, said air pipe j having an enlargement at its lower end adapted to receive disinfectant material, said enlargement comprising two separable sections. through the pipe C continues until the water 1 WILLIAM ALEXANDER FRASER.
